Chalk-/charcoal sketch of lunar crater Bullialdus

Recommended Posts

Dear all,

tonight I finished the weekend with a tiny sketch of the Eratosthenian-age crater Bullialdus (60km diameter) in the west of Mare Nubium. Apart from Bullialdus you can see Lubiniezky F in the North, Bullialdus A, and B south of the main crater and the tiny Bullialdus E and L in the west of it. Today I once again selected the small size of just 8x12cm for the sketch. Less chalk and less charcoal needed 😉


Telescope: Martini 10" f/5 truss-tube Dobsonian
Eyepiece: Celestron 25mm eyepieces with Baader Maxbright binoviewer
Date & Time: February 21st, 1940/ 2030 CET
Location: home terrace, Dusseldorf region, Germany
Technique: Koh-i-Noor charcoal, whitecoal and chalk blocks and pens on black sketching paper
Size: 8x12cm

Clear skies

I am serious, if you keep posting these then I will give up Lunar observing. Your Chalk Charcoal appear to better than my scope and eyeballs.👍

Your capture of the difference between light and dark is perfect. Other than your obvious talent this medium is ideal for the subject. Long may you continue so we can all enjoy.
